tically disappeared from the Navy, and there was little scurvy in Nelson's days; but the reason is not clear, since, according to modern research, lime-juice only helps to prevent it. It continued in the Merchant Service, and in a decade from about 1865 some 400 cases were admitted into the Dreadnought Hospital, whereas in the decade 1887 to 1896 there were only 38 cases. We had, at Cape Evans, a salt of sodium to be used to alkalize the blood as an experiment, if necessity arose. Darkness, cold, and hard work are in Atkinson's opinion important causes of scurvy.
Nansen was an advocate of variety of diet as being antiscorbutic, and Scott recalled a story told him by Nansen which he had never understood. It appeared that some men had eaten tins of tainted food. Some of it was slightly tainted, some of it was really bad. They rejected the really bad ones, and ate those only which were slightly tainted. "And of course," said Nansen, "they should have eaten the worst."
I have since asked Nansen about this story. He tells me that he must have been referring to the crew of the Windward, the ship of the Jackson-Harmsworth Expedition to Franz Josef Land in 1894–97. The crew of this ship, which was travelling to and from civilization, got scurvy, though the land party kept healthy. Of this Jackson writes: "In the case of the crew of the Windward I fear that there was considerable carelessness in the use of tinned meats that were not free from taint, although tins quite gone were rejected. . . . We [on shore] largely used fresh bear's meat, and the crew of the Windward were also allowed as much as they could be induced to eat. They, however, preferred tinned meat several days a week to a diet of bear's meat alone; and some of the crew had such a prejudice against bear's meat as to refuse to eat it at all."[1]
Of course tainted food should not have been eaten at all, but if it had to be eaten, then, according to Nansen, the ptomaines which cause scurvy in the earlier stages of decomposition are destroyed by the ferment which forms
